If you are going to head south to get out of January's persistent cold, here is a great and uplifting book for your trip . It tells the story of how the storm warning system came to be with stories of all of the lives that have been saved -- and, the courageous scientists who make the warning system possible. It is available in paperback or Kindle . If you prefer more drama, there is the story of the worst tornado warning failure -- ever. It occurred in Joplin, Missouri, on May 22, 2011, when 161 people perished when the tornado warning was badly botched. Like Warnings, When the Sirens Were Silent is written like a novel and is completely non-technical. Tragically, it demonstrates that triple digit fatalities from a single tornado will resume if/when the tornado warning system fails. In the case of Sirens, the paper version sold out very quickly. It is available in Kindle for just $2.99. This is an important story, so we priced it accordingly.
